1.) The number of visitors to the water park decreases as the temperature increases.
2.) The number of visitors to the water park increases as the temperature increases.
3.) The number of visitors to the water park increases as the temperature decreases.
4.)There is no correlation

Answer:

y = x - 10

Step-by-step explanation:

slope - intercept form: y = mx + b

y2 - y1         -4 - ( -8 )            4

---------   =   -------------   =   --------   =   1

x2 - x1           6 - 2               4

---------------------------------------------------------

y = mx + b

y = 1x + b

pick whichever point you want to use, for this I'll use (2, -8)

-8 = 1( 2) + b

-8 = 2 + b

-2   -2

-10 = b

y = 1x - 10 or y = x - 10

I hope this helps!

Answer: A) no solution

Step-by-step explanation:

1) 7x-3x+3=4x+6

2) 4x+3=4x+6

3) 3 is not equal to 6, so no solution

There is no solution of the given equation.

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

Given that;

The equation is;

7x - 3 (x - 1) = 2(2x + 3)

Now, Solve the equation for x as;

7x - 3(x - 1) = 2(2x + 3)

7x - 3x + 3 = 4x + 6

4x + 3 = 4x + 6

Subtract 4x both side;

3 = 6

Clearly, 3 is not equal to 6.

So, There is no solution of the equation.

Step-by-step explanation:

The surface area of the composite figure = the surface area of the bottom cuboid + the flank area of the top Cuboid

Answer:

1

 [tex]B  =  7.07 \  cm[/tex]

2

[tex]A  =848.4 cm^2 [/tex]

[tex]A_T  = 948.37 \  cm^2 [/tex]

Step-by-step explanation:

From the question we are told that  

   The lateral edge of a square prism is  [tex]d = 30 \ cm = 0.3 \ m[/tex]

    The angle of inclination is  [tex]\theta = 70^o[/tex]

    The volume of the prism is  [tex]V = 1500\ cm^3[/tex]

Generally the base of the prism is mathematically represented as

     [tex]B  =  \sqrt{\frac{V}{ d} }[/tex]

=>   [tex]B  =  \sqrt{\frac{1500}{ 30} }[/tex]

=>   [tex]B  =  7.07 \  cm[/tex]

Generally the lateral  area of the prism is mathematically represented as

       [tex]A  = 4 *  B  *  d[/tex]

=>     [tex]A  = 4 *  7.07  *  30 [/tex]

=>     [tex]A  =848.4 cm^2 [/tex]

Generally the total area of the prism is mathematically represented as

     [tex]A_T  =  2 * B  + A[/tex]

=>   [tex]A_T  =  2 * (7.07)  + 848.4[/tex]

=>   [tex]A_T  = 948.37 \  cm^2 [/tex]

Step-by-step explanation:

I guess, she is checking how FAR she runs each day (and not how fast ...).

how many more miles did she run on Friday ?

we get this by calculating the difference between the 2 values. that is what subtraction is for.

7 2/8 - 3 3/4

as long as we have the numbers as combination of full and fraction numbers, we can subtract the full numbers right away.

7 2/8 - 3 3/4 = 4 2/8 - 3/4

now we convert both numbers to full fractions :

4 2/8 - 3/4 = (32 + 2)/8 - 3/4 = 34/8 - 3/4

and then we bring both fractions to the same denominator, in this case 1/8 :

34/8 - 3/4 = 34/8 - 3/4×2/2 = 34/8 - 6/8 = 28/8

now we can simplify

28/8 = 7/2 = 3 1/2

so, she ran 3 1/2 miles more in Friday than on Tuesday.

FYI

I just wanted to show you the full formal flow of such a calculation.

but we could have gotten the result quicker by recognizing that we can simplify the numbers already at the beginning :

7 2/8 - 3 3/4 = 7 1/4 - 3 3/4 = 4 1/4 - 3/4 = 3 2/4 = 3 1/2

The most likely error is that, the student multiplied 27 by 3, after the first computation

Expressions are mathematical statements that are represented by variables, coefficients and operators

The expression is given as

(3^3)^1

As a general rule, we start by evaluating the expression in the inner bracket

So, we have

(3^3)^1 = (3 x 3 x 3)^1

Evaluate the products

So, we have

(3^3)^1 = (27)^1

Next, we evaluate the exponent

So, we have

(3^3)^1 = 27

The above implies that the value of the expression is 27 and not 81 as the student solved

The most likely error is that, the student multiplied 27 by 3, after the first computation

Hence, the value of the expression is 27 and not 81 and the most likely error is that, the student multiplied 27 by 3, after the first computation

Answer:  3 blocks

Step-by-step explanation:

18/6=3

Answer:

-12

Step-by-step explanation:

So to start we need to know what makes a line parallel. In an equation we know that for lines to be parallel they must have the same slope(m).

Then, we  need to know the slope-intercept form of an equation. The slope intercept form is [tex]y=mx+b[/tex] where [tex]m[/tex] is the slope of the line and [tex]b[/tex] is the y-intercept. In this problem where can see the second equation is already in this form.

Now that we know we need to find the slope, and we know that the second equation is in slope-intercept form we're going to convert the fist equation into the correct form.

To do this, we know we need to make sure [tex]y[/tex] is the only thing on the left side of the equal sign. Currently, on the left side of the equal sign we have [tex]-\frac{1}{2} y[/tex] so we have to divide both sides by [tex]-\frac{1}{2}[/tex] to get [tex]y=-12x -20[/tex]

Now that we have it converted to slope-intercept form, we are going to look for what represents the slope or [tex]m[/tex] in the equation. In this case the slope would be -12, so any line with a slope of -12 will be parallel.

Thank you

42 hours Susan worked this week to $378.

Given that, Susan's salary varies directly as the number of hours worked.

We need to find out how many hours did she work this week.

Direct variation is a type of proportionality wherein one quantity directly varies with respect to a change in another quantity. This implies that if there is an increase in one quantity then the other quantity will experience a proportionate increase. Similarly, if one quantity decreases then the other quantity also decreases. Direct variation is a linear relationship hence, the graph will be a straight line.

According to the question, last week she earned $144 for working 16 hours. This week she earned $378.

Let the number of hours she works this week be x.

So, the proportion is 144:16::378:x

⇒144×x=16×378

⇒x=42

Hence, 42 hours Susan worked this week to $378.

Rendell took 2.34 hr to cycle 42 km.

Rendell cycles 42 km at an average speed of 18 km/hr.
Distance = 42 km
Speed    =   18 km/hr

Speed is define as the distance covered per unit time,

Here,
Time = Distance / speed
